This is a wood-powered gasifier stove that produces gasoline runs your generator, runs your propane hot water heater, and heats hot water for you all off the grid.
STEP 1 : THE FIREBOX
Inside the firebox, I’ve got a gasification-style system built in there. One of the key things about a gasifying wood stove is that not only can I run it in a typical gasification wood stove manner, heat my home. But if I reverse that action with a fan and a draw system underneath the stove, with the ability to shut off the flow out the chimney pipe, and then draw down underneath the stove, reverse the action of the system, I can produce syngas that can go outside and into a generator.
This system has a little latch-up here at the top drops open so you can get in there and work the material around. By actually pulling the little latch out and the bottom of the main gasifier inside of there to shut it and rotate it locks into place.It is actually a dump plate on the bottom of the main gasification chamber so that all the ash and all the coal that’s not burned can dump out of the system into a tray below.
STEP 2 : THE SECONDARY BURN SYSTEM
A secondary burn system with two layers of stove pipe, one smaller inner diameter stove pipe, and one larger one is made for a better burn to take place with fresh air inlets right there in the chamber.
The outer sleeve stops below the bottom allowing air to travel up in between rising up to the pipe. There is a set of burner holes that makes sure to mix fresh oxygen that creates a swirl in there and helps burn any leftover syngas in the production system. So there’s no smoke coming out of this in the end.
STEP 3 : VENTURI SYSTEM
Inside the woodstove is the inner chamber that holds all your material, it gets hot and then creates an airdrop between this outer wall and the inner chamber wall that airdrop comes out these holes mix fresh oxygen into the top of the system with the smoke and burns it. The bottom holes allow air to dry in from the bottom to complete that burn as the material burns down to the bottom. It also works slightly as a venturi system as air is drawn up these walls towards these holes, creates a vacuum down here at the bottom holes and pull some of the smoke out a downward draw into the system and pull some of it into here helping mix some of the smoke With the air and will swirl it so it’ll burn cleanly.
The single air inlet hole is used to pull the smoke out of the bottom to reverse this process to put syngas out of this stove outside into a generator.
There is an inner set of holes in the bottom of the stove pipe. This helps mix air between the walls. The air gets drawn up between the wall since the inner pipe is longer than the outer pipe which mixes fresh air and completes the secondary burn to make sure there’s no smoke coming out of this pipe.
STEP 4: SYN GAS PRODUCTION
This is gonna be the bio-crude oil production system here which is basically another term for creosote that you produce from syngas production, otherwise known as gasification production.
It’s got just a single pipe rolling out of the backside of it which is connected to a creosote collection container.
As this gas starts to cool, it’s going to come up to here it’s going to work its way uphill, as it does so the hydrogen inside of the gas will be the lightest of all the gas is traveling uphill and definitely make it over the top much of the creosote we built re drip down into the second collection container here.
Now the rest of it’s gonna go up cross through the pipe here and come down to a condenser.
STEP 5 : THE REACTOR
The reactor shown here is made of two five-gallon steel cans. I cut the top off of one and the bottom off of another and slid them over each other. So they make a really long slide seal over each other with one pipe, as you can tell here, welded in. With an elbow, it’s a one-inch pipe coming out of the back of they’re welded in with an elbow.
STEP 6 : CRESOTE COLLECTION
The downward slope of the pipe force the smoke to release as much of this crude as it possibly can. Because it’s actually wanting to go uphill, which would be easy to smoke not going to cool real quickly. by forcing it slightly downhill, we’re forcing a lot of that heat energy out, making sure it’s releasing a lot of that, let’s call it creosote or bio-crude. It also allows for the creosote to roll down the bottom of the pipe into a container.
The gas moves through a reduction point which reduces the pressure. The gas gets refined and reduced slightly in volume through the system.
Hydrogen, carbon monoxide, and all the rest of the lighter gases are going to easily flow up this pipe through thermodynamic pressure. Now you’ve cooled a lot of that gas by running it downhill, trying to bring in into this lower container as much the second-grade creosote as you can, or biocrude. Now by running it uphill again, you can really force all the heavy hydrocarbons and other elements inside of this to focus on the hydrogen gas and the carbon monoxide.
This is a downhill pipe that’s going to go anti the direction of natural thermodynamic processes that’ll help condense out or precipitate out some of the oils at a much faster rate than it would be if that pipe was going in the natural thermodynamic flow direction. The first catch is going to be the heaviest and thickness of the current Crude oil.
It goes down that pipe from a reduction point here into the secondary catch. This comes up the hill here at the lighter gases not yet condensed, rises across loses a lot of energy and now is once again restricted into a quarter-inch copper gas pipe into a 5-gallon water tank with a 20 loop condenser coil inside.
The pipe out of that tank runs into a one-gallon pickle jar. The next pipe comes out of the top of the jar, we’re not actually trying to put it down too far because you don’t want to bubble and once it starts to fill with crude oil, you just want to grab them the lightest of the gases, the hydrogens, and the nitrogen, carbon monoxides and others that are still left within this system you want to grab, grab that right off the top.
Now it comes up this pipe here goes through the T and once again we have a secondary condenser that this goes through now it’s about four or five loops going through there, comes out through there. And that’s where the liquids gonna condense from this condenser that’s where it’s going to be caught. The liquid will be flowing, dropping the jug and the lighter Smoke will continue on now down the pipe.
The result of the bio-crude oil project collected 4 grades of oil. So the next step of this project now is to put this all through the refinery, which will actually be connected inside the woodstove that made all of this.
So in the end, what we’ll have is all the liquid being produced the crude oil once again, flow back to the woodstove go through the refinery out the refinery tower, and on the other side, we’ll have a high-grade fuel to use in any engine.
